摘要
在甘薯疮痂病胁迫下,抗病性不同的甘薯品种金山1255(感病)和广薯8870(抗病)染病后,叶片细胞的超微结构都发生了变化,最敏感的部位均是细胞膜;活性氧产生的两个主要部位(叶绿体和线粒体)也受到了不同程度的攻击;感病品种的叶绿体和线粒体外膜外突成致密的小球,产生了大量的吞噬体,抗病品种则产生了大量用于修复细胞膜的高尔基小泡.
Under sweet potato scab (Sphaceloma batatas Sawada) stress, the ultrastructure changed in two sweet potato varieties with different responses to sweet potato scab stress (Guangshu 88-70-disease resistant, Jinshan 1255-disease sensitive). The most sensitive part was cell membrane. Mitochondrion and chloroplast which produced active oxygen were decomposed at different rates. There were lots of phagosome in sensitive variety and lots of transitional vesicle in resistant variety. The transitional vesicle were closed related to repair-deficiency of cell membrane.
